2 NOTES FOR THE TEACHER SHAPE AND SPACE SUGGESTED TIME 5 hours TEACHING OBJECTIVES Recognise reflective symmetry and reflect shapes in a mirror line. Measure and draw lines to the nearest millimetre. Recognise directions, and perpendicular and parallel lines. Understand and use degrees. Use a protractor to measure and draw acute and obtuse angles to nearest. Calculate angles on a straight line. Identify, estimate and order acute and obtuse angles. Make patterns from rotating shapes. Recognise and explain patterns and relationships, generalise and predict. SECTION Line symmetry and reflection SECTION Measuring angles SECTION Naming and estimating angles SECTION Drawing angles SECTION 5 Calculations involving angles HOMEWORK Section, Star Challenges and on symmetry. Section, Star Challenge 5 is designed to reinforce mathematical language. Consolidate the use of a protractor to measure and draw angles. CROWN COPYRIGHT 00 8
3 PART CHECKLIST Unit Checklist for pupils Line symmetry and reflection You will: recognise reflective symmetry reflect shapes in a mirror line Measuring angles You will: use a protractor to measure angles to the nearest degree Naming and estimating angles You will: classify angles according to type and size estimate the size of angles Drawing angles You will: draw angles to the nearest degree draw and measure lines to the nearest millimetre Calculations involving angles You will: use the fact that angles on a straight line add up to 80 work out the size of unknown angles without using a protractor CROWN COPYRIGHT 00 9
4 SECTION : LINE SYMMETRY AND REFLECTION DIRECT TEACHING POINTS Provide opportunities for practical work to reinforce this learning. Illustrate line symmetry in a variety of contexts and check pupils understanding. It is important to demonstrate examples where the line of symmetry is not parallel to the edge of the page exercise. Star Challenges and illustrate the level of difficulty required at Level. KEY VOCABUL ARY mirror line line symmetry reflect reflection TO LEAR USE AND CROWN COPYRIGHT 00 50

8 SECTIONS, AND : MEASURING ANGLES NAMING AND ESTIMATING ANGLES DRAWING ANGLES DIRECT TEACHING POINTS Consolidate measuring length (from Unit ) before going on to measure angles. Clarify the meaning of angle as a measure of turn and correct any misconceptions about its size being related to the length of the arms. Use an OHP to demonstrate the use of a protractor. Emphasise the correct use of the scale. Provide opportunities for pupils to use protractors with increasing accuracy. Measure this angle. I put the protractor like this. What did I do wrong? Teach the classification of angles and the use of correct vocabulary. Exercise provides practice. A right angle 90 An acute angle is less than 90 An obtuse angle is between 90 and 80 A reflex angle is bigger than 80 Model how to estimate the size of an angle using benchmarks such as 90, 80, and 5. Exercise and Star Challenge provide examples for discussion. Pupils need immediate feedback on their estimates in order to improve this important skill. Demonstrate the construction of triangles as in Section exercise. This is a sketch of a triangle. It is not drawn accurately. You are going to draw the triangle accurately A Start with the line BC, which is 0 cm long. Draw angle B, which is 0, then angle C, which is Extend the lines made by these angles so they B 0 cm cross. This is point A. Star Challenge 7 is quite demanding.
